There is NO FUCKING WAY this trash manga sold 145 MILLION copies. I refuse to believe that claim.
Also, Shigemi goated, as always.
The others have corrected on the number so this is just my 2 cents:
1. It's like watching a car crash, you simply can't look away.
2. The manga doesn't take itself seriously and it's different from many many many isekai slow life with my slave harem thing. And the characters have sex, like having sex, unlike those isekai manga that have sex bomb characters but refuse to let them fuck (magazine reason or other usual tropey bullshit reasons).
3. The fans bought it for Shigemi.
I'm glad they're still buying things in japan at least.
